Thank you for the reply, can any of the TP Link routers cope with more than one IPv6 WAN?

I have a ER7206 with two WANs both IPv6 I can one or the other working IPv6 but not both, if you setup the second one internet access stops. Also it is not possible to set up the IPv6 so when WAN one...

@Peterdevon The IP address starts 2a0c:4f42 and the clients are getting one with the same prefix with a number at the end Thanks

@Clive_A I have an IP address and so do the clients

I am obtaining IPv6 address on WAN side and on devices on the network, I am presuming I am not getting IPV6 access because of the ACL rules
